Copper-Catalyzed Synthesis of Indol-3-yl α-(Difluoromethyl)-α-(trifluoromethyl)carbinols: Construction of Difluoromethylated sp<sup>3</sup> Carbon Centers
through a Friedel–Crafts-type mechanism, and a variety of indoles with commonly occurring functional groups such as formyl, cyano, nitro, alkyloxide, and halogen are well tolerated. In addition, these carbinol products are readily transformed into diversified difluoromethylated dinitrile indol-3-yl derivatives. This strategy provides a general synthetic method for ready construction of difluoromethylated
Immobilized Pd on a NHC functionalized metal–organic framework MIL‐101(Cr): an efficient heterogeneous catalyst in Suzuki−Miyaura coupling reaction in water
A novel Pd−NHC functionalized metal–organicframework (MOF) based on MIL‐101(Cr) was synthesized and used as an efficientheterogeneouscatalyst in the C‐C bond formation reactions. Using this heterogeneous Pd catalyst system, the Suzuki−Miyaura coupling reaction was accomplished well in water, and coupling products were obtained in good to excellent yields in short reaction time. The Pd−NHC−MIL‐101(Cr)

An efficient catalytic system of CuI/8‐hydroxyquinalidine was developed for the coupling of aryl iodides and indole as well as some azoles. The reaction could be carried out at 90°C under the condition of relatively low catalyst loading, affording various N‐arylindoles and N‐aryl azoles in good yields. The functionalized and hindered aryl iodides were suitable substrates for this transformation.
